Rocks and Minerals Lessons 1-4
Rocks and Minerals Lesson 1: Minerals
What is a mineral? • Solids • Inorganic - not living • Natural - not made by humans and found in the ground • Definite crystal structure - atoms are arranged in a predictable way • Definite chemical composition
Formation of Minerals • Form as magma and lava cools – known as crystallization • Form in water as precipitates - an insoluble solid that separates from a liquid solution • Can be weathered by physical and chemical methods • Form by changes in pressure deep beneath Earth's surface - as the pressure increases, minerals combine to become new minerals

Uses of Minerals • Uranium – fuel for nuclear power plants • Silver – electronics, jewelry, developing photographs • Lead – batteries • Bauxite – aluminum foil, soda cans, airplane parts • Copper – pipes, wire, other parts of industry • Gold – jewelry and industry • Other products that have minerals – lighbulbs, MP3 players, cereal, cell phones, furniture, powders

Rocks and Minerals Lesson 2: Rocks and the Rock Cycle
Types of Rocks • Igneous Rocks – forms when magma cools and crystallizes
Types of Rocks • Sedimentary Rocks – forms from the breakdown of rocks by physical and chemical means then compacts and cements together
Types of Rocks • Metamorphic Rocks – forms when rocks and minerals are subjected to extreme changes in temperature and pressure
The Rock Cycle Intrusive or Extrusive deposition lithification

Rocks and Minerals Lesson 3: Rocks and Minerals as Resources
Mining Rocks and Minerals • Extract Rocks and Minerals from the Earth • Valuable – lots of uses in our daily lives • Mining Techniques • Consequences (pros and cons) • Ore • Reclamation • Economy • Environment • Society
Mining Operations/Techniques • Depends on the type of rock or mineral being mined • Most have heavy machinery moved into the area and dig for the resource • Panning • Extraction from Caves • Dynamite
The Good, the Bad, and the Ugly What else? ProsCons • Environmental Practices put into place • Build terraces to prevent erosion • Planting • Jobs • Reclamation • Destruction of Environment • Trees • Farmland • Houses • Erosion • Water shortages

Rocks and Minerals Lesson 4: Soil and Soil Conservation
It’s Time for Vocabulary • Soil - a thin layer of material on Earth's crust composed of sediments, gases, moisture, and organic matter. • Organic Matter -
It’s Time for Vocabulary • Soil - a thin layer of material on Earth's crust composed of sediments, gases, moisture, and organic matter. • Organic Matter – decomposing plant and animals material or DOM (dead organic matter) • Soil Composition - the types of materials that make up soil • Parent Rock - the primary rock type that forms the soil
Soil Horizons Climate is important in determining the types of soils that form Parent Rock
